The change shouldn't have any adverse effects, but what I'm
curious about is why 'smb_read_error' was zero at that point ?

All paths through that code should end up setting 'smb_read_error'
nonzero on error or timeout. Did you reproduce this ? Is so, set
the debugger to break on "read_socket_with_timeout()" and walk
through the function. Tell me how it exits on timeout with
smb_read_error == 0. That's where the real bug is. The patch
you added may just be a band-aid on this.
